Ate here for breakfast. As per a previous review, ordered the eggs with bacon, sausage and it came with a little salad and I got the rice and miso soup side. My only concern was the miso soup as I knew barley is not often identified as an allergen in Japanese foods. A really nice breakfast option though and very filling.
You have to look carefully, but if you do you will be well rewarded for your efforts. The Denny’s menu contains allergen information for each dish in the fine print under the dish name. The word for wheat is 小麦. I had one of the breakfast options (eggs sunny side up, ham, and sausage) with one of the carb options (rice and miso soup). Well worth the effort in figuring it out.
